In this video, David Atkins explains how a 'gappy downswing' is caused by the trail elbow lifting too far behind the body at the top of the swing. He demonstrates a corrective drill using a glove under the trail armpit to help golfers maintain wrist angles and improve shaft lean at impact. By focusing on a tighter elbow position and an abbreviated follow-through, players can stop losing power and control.
A 'gappy downswing' occurs when the trail elbow works too far behind the body at the top of the swing.
Losing connection under the trail armpit causes an early loss of wrist hinge and shaft lean.
Using a glove under the trail armpit provides immediate feedback on whether the arm is staying connected.
Stopping the follow-through short helps reinforce keeping the elbow close to the midline during the downswing.
Correct trail arm positioning prevents 'casting' and helps maintain compression through impact.
